you have a nice ring thank you.I ____it since I got married.
A.had B.bought C.have had D.have bought
since后面不是加时间点吗?那为什么买要换为延续性动词had呢?

since 可用作介词、连词、副词
用作连词时,可表时间（自.以来）,一般为过去时态；也可表原因（既然）.
作介词时,接名词性短语,表“自.以来”.
上面的题目是since作连词的用法,表“自.以来”.since引导的从句可以是延时性动词,也可以是瞬时性动词,但主句是肯定句的语,一般是延续性动词,否定句可是非延续性动词.
如,it's five years since she lived in Beijing.她不在北京已经有五年了.
i have not seen her since she left.从她离开后,我就没有见过她了.
